The three prominent music trade magazines that published record popularity charts back in the day (Billboard, Cashbox, and Record World) based their national singles charts on a combination of record sales and radio airplay, with each magazine having their own statistical equations to rank the records.
A fourth publication, Radio & Records, published singles charts based exclusively on radio airplay; sales figures weren’t factored into their charts.
In the case of this single, the two sets of charts showcased the occasional disparity between a single’s sales and the airplay it received on the radio. The single peaked at #7 on the Billboard Hot 100 and the Record World Singles Chart and at #6 on the Cashbox Top 100, but the radio airplay it received was so strong that on the R & R singles chart, it was a #1 single.
Either way, it’s a gorgeous song. Released this week, 41 years ago…
